Buzz Desktop v0.5.1: native Claude/GPT routing, claude-opus-5 support, MCP proxy/TLS passthrough
Buzz adds native gateway routing for Claude and GPT model families, an explicit claude-opus-5 model config entry, and fixes Anthropic prompt caching when used through Databricks with MCP proxy/TLS passthrough. The desktop app gains inline custom harness creation from agent dialogs, Linux WebKit rendering workarounds, and several UI fixes. The CLI gets a NIP-38 profile status command.
